*At the University of Iowa more than ten years ago, a Chinese physics student shot five people to death, among them two professors involved in highly sensitive research. He wounded one person, permanently paralyzing her. Then he committed suicide. Some believe he was under orders from a foreign government.
*A law student from Nigeria shot two faculty members and a student in 2001 at Appalachian School of Law in Grundy, Virginia.
*Not too long ago there was a shooting at a college in Ohio by someone from India or Pakistan?
